Loctite 574 is a high-performance anaerobic flange sealant designed for sealing close-fitting rigid metal flanges, particularly on gearboxes and engine casings. This product cures in the absence of air when confined between close-fitting metal surfaces, providing excellent resistance to oil, water, glycol, and other chemicals. It prevents leakage and corrosion, offering reliable sealing without the need for traditional gaskets. The sealant has a high viscosity and fills gaps up to 0.25 mm, ensuring a robust and durable seal. It is suitable for applications requiring fast curing and high temperature resistance.
